FAQ

FAQ

1. Insulating Oil Tester Series
1.1 What is the main function of the Insulating Oil Dielectric Strength Tester (80kv/100kv)?
Tests insulating oil's dielectric strength to detect impurities, moisture, or aging, ensuring safe operation of transformers and circuit breakers.

1.2 How often should the Insulating Oil Dielectric Strength Tester be calibrated?
At least once a year; shorten intervals for frequent use, harsh environments, or post-maintenance.

1.3 What is the difference between the Closed Cup Flash Point Automatic Tester and the Open Cup Flash Point Automatic Tester?
• Closed Cup: Tests in sealed containers; for low-flash oils (e.g., diesel) and sealed power equipment.

• Open Cup: Tests in open containers; for high-flash oils (e.g., insulating oil) and air-exposed scenarios.

2. Transformer Test Series
2.1 What can the Transformer Capacity Tester detect?
Detects transformer's actual capacity, no-load/load loss, no-load current, and impedance voltage; judges compliance and faults.

2.2 How to use the Transformer Tap Changer Tester?
1. Connect test lines to tap changer terminals per manual.

2. Power on, select test mode (e.g., resistance test).

3. View results; disconnect and power off after. (Note: De-energize and ground transformer first.)

2.3 What is the purpose of the Transformer Winding Deformation Tester?
Detects winding deformation (axial displacement, short circuits) from short-circuits or vibration; enables early maintenance to avoid accidents.

FAQ
